东莞大堤寮步段裂缝原因分析及除险加固设计

Crack Analysis of Reinforcement for Liaobu Section of Dongguan Embankment

该文依据现场调查、收集整理地质勘察和沉降监测报告等资料,对东莞大堤寮步段(桩号14+230~15+030)堤顶裂缝原因进行分析,认为大堤裂缝产生内因是地基有软弱土层以及新旧路基搭接软硬不均,外因为交通量激增因素、内外江水流交替作用、东引运河清淤工程、路面排水不畅等等;同时依据上述原因分析提出针对性的除险加固设计,可供相关类似工程加固设计参考。

Based on on-site investigations,geological surveys,and settlement monitoring reports,this article analyzes the reasons for the cracks on the top of the Dongguan Embankment Liaobu section(pile numbers 14+230~15+030).It is believed that the internal causes of the cracks in the embankment are weak soil layers in the foundation and uneven hardness of the new and old roadbeds,as well as factors such as the increase in traffic volume,the alternating effect of internal and external river flows,the dredging project of the Dongyin Canal,and poor road drainage.At the same time,based on the above reasons,targeted risk elimination and reinforcement designs are proposed for reference in similar engineering reinforcement designs.
